2 Post-Earthquake Response & Recovery Services Experience The startling frequency of large devastating earthquakes that have recently occurred around the world are a potent reminder about the importance of disaster preparedness of our communities. After such large-scale disasters involving buildings, bridges and critical urban infrastructure, assessing the damage and safety of our infrastructure is one of the most important first steps to disaster recovery. People are scared to return to their damaged homes, offices and public spaces. The displaced public places an even greater demand on disaster response and recovery resources. Post- Earthquake, Windstorm and Flood Safety Evaluation of Buildings (ATC-20 and ATC- 45) are the de facto standards for post-disaster safety evaluations of buildings in the United States and around the Pacific Rim. ATC-20/45 training is critical for our nation s disaster preparedness to quickly assess building safety in the aftermath of a major disaster. Reid Middleton is regularly asked to lead such training events for clients including the U.S. Navy, Port of Seattle, ASCE in Costa Rica, Washington State General Administration, University of Washington, Bellevue College, and Vulcan Northwest: Structural engineering at Reid Middleton has focused on renovation, preservation, and expansion projects. Over the past seven years, we have designed more than 90 seismic upgrade and renovation projects and more than six million square feet of new buildings. We have performed FEMA 154 seismic screening for over 500 buildings leading to innovative seismic risk reduction programs for our clients such as the U.S. Navy, Seattle Tacoma International Airport, Anchorage International Airport, Alaska Airlines, City of Seattle, City of Tukwila, among others. A sampling of our post-earthquake evaluation experience includes: City of Seattle Post-Nisqually Earthquake Response & Recovery ATC-20 Evaluations of 1,500 buildings U.S. Navy Post-Nisqually Earthquake Safety Evaluations ATC-20 Evaluations of 47 buildings at Naval Base Kitsap-Bremerton and Keyport, WA Elevated Water Tanks Seismic Evaluation & Retrofit, Renton, WA 2 elevated water tank seismic evaluation and upgrades using FEMA 346 Green Lake Shell House, Seattle, WA Hiawatha Community Center, Seattle, WA Post-Nisqually Earthquake Safety Evaluations & Engineering Coordination, City of Seattle, WA Renton Highland Water Tank Seismic Retrofit Renton, WA Grays Harbor County Courthouse Seismic Evaluation & Upgrades Montesano, WA City of Des Moines Post-Nisqually Earthquake Evaluations, WA ATC-20 Evaluations of City Hall, Senior Center, Field House, and bridges City of Renton Post-Nisqually Earthquake Evaluations, WA ATC-20 Evaluations of several office and commercial buildings Alki Beach Bathhouse, Seattle, WA Juvenile Detention Facility Evaluations Post-Satsop and Post-Nisqually Earthquake Grays Harbor County, Montesano, WA Performance regarding Naval Hospital Bremerton Seismic Upgrades The seismic renovation project was complex and challenging. While our primary goal was to improve the seismic performance for the hospital, a secondary goal was to perform the work in our operational hospital without significantly impacting the medical mission. Reid Middleton utilized innovative methods to satisfy both of these goals. Russ Kent - Facility Manager Naval Hospital Bremerton 2

Rapid Evaluation & Assessment Program (REAP) Earthquake Preparedness The Rapid Evaluation & Assessment Program (REAP) empowers facility management to quickly and accurately perform detailed building safety evaluations immediately after an earthquake. The system reduces delay in evaluating and posting essential facilities, gives the assessment team customized building specific information, pre-engineered guidance, and minimizes unnecessary delays. An innovative use of state-of-the-art technologies, REAP incorporates ATC-20 and Performance-Based Earthquake Engineering criteria into a system of seismic monitoring of the structure accessible via graphic user interface, post-earthquake evaluation field manuals, and training. Performance regarding Naval Medical Center San Diego REAP The Rapid Evaluation and Assessment Program (REAP) is a customized post-earthquake response tool that utilizes seismic sensors deployed at critical locations in our buildings to help us quickly and accurately assess the safety of the facility after a major earthquake. The NMCSD Seismic Improvements Program has significantly improved our seismic safety and preparedness and is a model program for other hospitals and critical facilities in high seismic areas.
